Openflowkit Mcp
vrun-design/openflowkit
Lets Claude Desktop, Cursor, and Windsurf create and manipulate flowcharts, architecture diagrams, and other structured visuals in the OpenFlowKit web app running locally. You can ask your AI assistant to generate diagrams from natural language, paste Mermaid syntax that gets auto-enriched with 1,600+ tech icons, export to MP4 walkthroughs, or edit the bidirectional diagram-as-code DSL. The server acts as a bridge so your editor can drive the full OpenFlowKit canvas without leaving the chat window. Useful when you're documenting systems, explaining architectures to teammates, or prototyping data flows and want the diagram to live alongside your code with zero cloud dependencies.

Install
From registry metadata$ npx add-mcp @vrun-design/openflowkit-mcp --name openflowkit-mcpRun in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
Other ways
Claude Code
$ claude mcp add openflowkit-mcp -- npx -y @vrun-design/openflowkit-mcpRun in your terminal. Replace YOUR_* placeholders with real values; add --scope user to install for every project.
